US Patent 7830582 Electrochromic display

An electrochromic display is disclosed which comprises an array-side substrate (10) in which a pixel electrode (15) and an electrochromic layer (30) are formed, a color filter-side substrate (50) in which a counter electrode (53) and an electrochromic layer (54) are formed, and an electrolytic layer (80) injected between the array-side substrate (10) and the color filter-side substrate (50). By forming a partition wall (23) on the periphery of the pixel electrode (15) and the electrochromic layer (30), there can be prevented short-circuits between pixel electrodes (15) and short-circuits between electrochromic layers (30) between adjacent pixels, thereby realizing an electrochromic display with higher precision.
